Given numbers are 558,681,809,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,681,809,908 is 204945588.
Find LCM of 558,681,809,908 with Prime Factorization
2 | 558, 681, 809, 908 |
3 | 279, 681, 809, 454 |
227 | 93, 227, 809, 454 |
93, 1, 809, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 227 x 93 x 1 x 809 x 2 = 204945588
Therefore, the lowest common multiple of 558,681,809,908 is 204945588.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
558 x 681 x 809 x 908 = 279135890856
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
681 : 1, 3, 227, 681
809 : 1, 809
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,681,809,908, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
681:3x 227
809:809
908:2x 2x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 227 = 1362
Therefore, the value for common factors is 1362.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 279135890856/(1x1362)
LCM = 279135890856/1362
LCM = 204945588
Thus, we can understand that the LCM of 558,681,809,908 is 204945588.
